GODDU MACHINE FOR USE IN THE MANUFACTUREAOF SHOES Filed July 5, 1924 Sheets-Sheet 4 Patented Jan. 7, 1930 UNITED STATES PATENT OFFICE GEORGE GODDU, OF WINCHESTER, MASSACHUSETTS,ASSIGNOR TO UNITED SHOE IMA-` CHINERY CORPORATION, OF PATERSON, NEW JERSEY, A CORPORATION OF NEW JERSEY MACHINE FOR USE IN THE MANUFACTURE OF SHOES Application led July 3, 1924. Serial No. 724,136.

This invention ielates to machines for use in the manufacture of shoes` and is herein shown as applied to a lasting. machine adapted for use in the manufacture, among others, of shoes of that type in which the outsole is secured to the insole by through-andthrougli stitches, i. e., stitches which, at least at the time of their insertion, penetrate to the inside of the shoe.

In a co-pending application Serial No. 721,007, filed June 19, 1924, I disclosed and claimed a novel method of making shoes of the above-mentioned type, having for an object to elect economies in the production of such shoes and at the same time to provide shoes ot superior quality by dispensing with side lasting tacks either as permanent parts of the shoes or as temporary astenings. In accordance with the procedure illustrated and described in that application, the insole was provided with a lip on its bottom tace, either by channelingit or'by securing to it a piece ot' material such as canvas tape, and in the progressive last-ing of the sides of the shoe the upper was fastened to the lip by line wire staples. VThe shoe could thus be made without the extra operations involved in the use of temporary lasting tacks and Without the delay required in waiting tor the upper to set in lasted shape when such tacks are used. The shoe, moreover, was of superior quality, since the upper was secured permanently in its original lasted condition to the insole by fastenings of such a character and so applied as not to penetrate to the inner face of the insole nor to detract appreciablyfrom the iexibility of the shoe.

The present invention, in one important aspeet, has in view the provision of means for eiecting still further economies and improvements in the manufacture of throughand-througli sewed shoes. It is sometimes desired, for purposes of economy or in order to provide a more flexible shoe, to use an insole which is so thin or of suchquality that it cannot be provided with a channel lip which will successfully withstand the'strain of the upper if the upper is fastened to it in the lasting of the shoe. Likewise, for the sake of economy or for other reasons, itmay not be desired to attach a tape to the insole to serve as .a lip. To meet these conditions the present invention, in one important aspect, provides a lasting machine so constructed and organized as to fasten the upper permanently4 While under lasting strain to the intact substance or body of the insole, as distinguished from a lip or from any part weakenedby a channel or other incision, by fastenings that are anchored in they insole without being clinched on its inner face. To render the fastenings eliective to hold the upper, they are anchored, as herein illustrated, b vdrivinO them in curved paths Within the su stance 0I the insole. In the 'operation of. the machine herein shown, the astenings are curved in such manner that their ends are directed reversely toward the outer or bottom face of the insole Without penetration of its inner face. The ends of the fastenings thus inserted may or may not emerge from the bottom face of the insole, since in either case they are entirely embedded in or covered by the shoe bottom materials after the outsole hasv been applied.

While in-many of its aspects the invention isV not limited` as tothe' character of the fastenings utilized, it is considered preferable to use line Wire staples, since fastenings of that character have' been found amply eliecftive for holding the upper in lasted positionl and at the same time do not detract appreciably from the tlexibilit of the shoev nor areV otherwise objectiona le as permanent parts of the shoe. The staples are anchored tothe shoe by they curvatureV of their legs within the substance of the insole. As herein illustrated both legs of each staple are curved in the same'direction in planes that are sub-V stantially perpendicular to the cross-bar of the staple, although'll'in its more general aspects the invention is not limited to means for curving the legs in this particular manner. The machine shown is also provided with means for forming the staples, although the invention is not limited to a machine including staple forming means.

lVhile tlirough-and-through seWed shoes are referred to above as shoes of a type in the manufacture of whichl thev invention oers particular advantages, it will be evident that in so far as the invention provides novel means for lasting an upper over an insole in the manner disclosed it is not dependent upon the particular character of the outsole-securing operation. Furthermore, it is considered that the invention is not limited in utility to the manufacture of shoes having both insoles and outsoles, and, accordingly, the term sole is used in the claims in a generic sense to designate that part to which the upper is fastened in the lasting operation.

The invention will now be more particularly set forth by reference to the accompanying drawings and thereafter pointed out in the claims.

Theinvention is herein illustrated as applied to a machine of the same general type as that'shown and described in my prior application Serial No. 653,291, filed on July 23, 1923, and embodying various features claimed in that application. A f i The machine includesV in its organization means for pulling the upper over the last comprising a gripper having a pair of jaws of which the lower one 30 is iixedly secured, as at 32, to the lower end of a bracket member 34 of a sleeve member 36 mounted for vertical. sliding movement in a bearing 38 which is mounted for rocking movement in theiforward end of a horizontally movable slide 40. The other jaw 42 is connected to the lower end of a rod 44, inside of the sleeve 36, by means of a short link 46, the body portion of the jaw 42 being also connected by a pivoted link 48 to the bracket member 34 which carries the jaw 30. It will be understood that reciprocation of the rod 44 will cause movement of the jaw 42 in directions toward and from its co-operating jaw 30 to seize a portion of the upper of a shoe interposed between the serrated ends of the jaws and to release it. Both jaws are moved together in an upward direction to effect the updraw movement by which the upper is pulled upwardly to tension it onthe last. To cause the updraw movement just described, the upper end of the sleeve 36 is connected, by a ball-and-soclret joint indicated at 50, to the forward end of a lever 54 pivoted at 56 (Figs. 1 and 2) on the frame or head 58 of the machine. For rocking the lever 54 there is connected to its rear end a slide 62, the slide having a reduced rod part 64 which passes slidably through a block (not shown) pivoted at in the lever 54, said slide carrying at its lower end a pin and roll 66, the roll being mounted in a cam groove 68 in a cam wheel 7 0 arranged to be clutched to a shaft 71, which is the driving shaft adapted to be controlled from connections 73 leading to a treadle (not shown). Upon rotation of the camwheel 7 0 the slide 62 and connected rod 64 are reciprocated and during downward movement thereof apply yielding pressure through a spring 72 upon the rear end of the lever 54, thus effecting a yielding updraw movement of the gripper at the front end of the lever.

Extending through the sleeve 36, as before mentioned, is the rod 44, the upper end of which also passes through the ball member of the ball-and-socket joint 50 so that the upper end of said rod may be engaged to force the rod downwardly, thus closing the gripper. For thus forcing the rod 44 downwardly there is provided a shaft 8O (Figs. 1 and 2) mounted rotatably in a bearing 82 carried by the forward end of the lever 54 and a second bearing 83 in the end of the rotatable pivot 56 upon which the lever 54 oscillates. Fixed to the rear end of the shaft is an arm 84 carrying at its lower end a roll 86 adapted to contact with the periphery of a cam wheel 88 fixed on the shaft 71, whereby the arm 84 and shaft 8O are rocked about the axis of the shaft. Secured to the other end of the shaft 8O is another arm 90 having a spring-controlled plunger therein provided with a socket 92 (Fig. 2) to receive the upper end of the rod 44. `For returning the rod 44 upwardly after a depression thereof there is provided a spring 1,00 surrounding the sleeve 36 and resting at its lower end upon the upper end of the bearing 38, its upper end pressing against a washer 102 slidable on the sleeve 36 and co'nnected to transmit upward movementto the rod 44 by a pin 104 fixedly secured to the rod 44 and extending through a slot 106 in the sleeve 36. Clamped to the sleeve 36 is a collar 108 which is adjustable on the sleeve to vary the position of the pin 104 when at its upper' position of rest, thus setting a limit to the upward movement of the rod 44 and of the upper gripper jaw 42 relatively to the sleeve 36.

As before stated the sleeve 36 is slidablv mounted in the bearing 88 at the forward end of the slide 40. For reciprocating the slide 4 the latter is provided intermediate between its ends with a stud carrying a roll 1,12 (Fig. 2) the said roll being held yieldingly against a face cam 114 on the cam wheel 88 by a' spring pressed lever 118 which engages the end of the slide, there being a washer of hardened fibre 120 between a head on the end of the slide and 'a portion of the frame to limit movement of the slide. For tensioning the spring which operates the lever 118 in one direction there is provided a hand lever 122, a pawl 124 and a ratchet wheel 126. all of which operate in a common and well-known manner. It will be understood that upon rotation of the shaft 71, to which the cam wheel 88 is fastened, the slide 40 will be moved to the right in Fig. 2, at which time the gripper jaws 30, 42 are open in a position to seize the edge of the upper of the shoe, this movement of the slide being caused by the high portion of the cam 114. Continued rotation of the cam brings the roll to the low portion thereof, to cause the slide 40 to be actuated by the spring pressed lever 118, as before described, so that the movement of the slide 40 toward the left in Fig. 2 is produced yieldingly and the closed gripper jaws 30, 42 are given their overdraw movement to pull the edge of the upper inwardly over the edge of the last. For a more detailed description of the means thus far described for causing the closing of the gripper and for effecting the updraw and overdraw movements of the gripper reference may be had to Patent No. 584,744 granted June 15, 1897, upon applica.- tion of S. lV. Ladd and R. F. McFeely.

Means is preferably provided for varying the tension of the spring 72, the said means comprising a sliding wedge (Fig. 2) having a plurality of cups or seats 132 for a pin 134 in a block 136 slidable on the lower' end of the rod 64, the arrangement being such that movement of the wedge 130 toward the left in Fig. 2 will raise the block 136 to compress the spring, thereby exerting greater pressure upon the rear end ofthe updraw lever 54 which will be manifested during the updraw movement of the gripper. For operating the wedge 180 there is connected thereto a rod 188 the forward end of which carries a handle in a position accessible to the operator so that the wedge may be adjusted as desired. This adjustment mechaspecially constructed to form the staple in l one plane and subsequently transfer it to the plane of the driver element. Moreover, the staple forming and driving devices are, for the most part, so mounted as to be retractable and projectible with respect to a stationary work rest a which is fixedly carried by a bracket 152 on the head or top frame 58 of the machine. The said work rest 150a is a curved member, as most clearly shown in Fig. 2 of the drawings, having its'end portion provided with a roughened surface to contact with the work to position the same.

In the villustrative staple forming and inserting means, there is provided an inside former (Fig. 4) supported stationary in a bracket 162 fixedly securedto the top frame 58 of the machine, the inside former being carried by a shank part 164 secured for adjustment by a screw, as indicated at 166. All of the rest of the staple forming and guiding devices (excepting the stationary cutter) are carried at the forward end of a reciprocable slide 17 0 (Figs. 1 and 2). For reciprocating the slide in an inclined guideway 178 in the frame 58, there is provided a lever having an adjustable fulcrum at 177 on the frame and a roll at its upper end for engagement in a cam groove 179, the lower end of the lever being connect-- ed yieldingly to a link 181 pivoted at 183 to the. slide 170. It will be understood that the slide is operated in time relation to the gripper mechanism and to the operations of the fastening forming and driving devices carried by the slide.

As shown, the outside former 171 (Fig. 5) comprises two plates 1.72, 174 secured to a slide bar 176 which is vertically reciprocated, as will be hereinafter described, the

staple forming movement taking place as the slide 17 0 moves toward the work rest 150. Also carried by the slide 170 is a cutter 180 adapted to shear the wire fw in co-operation with a fixed cutter 182 carried `by the stationary bracket 162. In order that the wire w may be properly guided across the end of the inside former 160-there is provided a pair of slotted sidevguide members 184 which support the wire while the end thereof extends across the space closely adjacent to the en'd of the inside former, the extreme end of the wire being in Contact with an adjustable abutment-186 carried by the fixed bracket 162. The guide members 184 are so positioned in relation to the staple guiding and driving devices that upon forward movement ot the slide 170 they move along opposite sides of the inside former 160, and just before they pass from the wire the cutters operate to sever it and at the same time the outside former members 172, 174 engage the wire as indicated in Fig. 9, to press it against the iace ot' the inside former. By continued movement the outside former forms a substantially Ushaped staple, as most clearly indicated in Fig. ot' the drawings. Just at the completion oi' the forming movement of the outside former, the cross-bar of the `staple is engaged by a die member 190 at the lower end of a plate 192 lined to the forward face of a casing 193 which forms a housing for the bar 17 6, the die operating in the space between the outside former members 172, 174 to engage` the cross-bar of the staple to maire a straight cross-bar in co-operation with the tace or end of the inside former 160.

At the end of the forward movement oi the slide 170 the staple is fully formed, as indicated in Fig. 10. By the time that the staple is fully formed the rear edge of a staple controller member 198 (Fig. 7) which 1. moves forwardly with the outside former, is

in alinement with the operative tace of the inside former 160. Hence, as the outside 'former moves downwardly, to transport the staple to the driving plane, the staple is caused to straddle the controller member 198, the latter thereby maintaining the staple properly within the grooves 200 (Fig. 11) in the outside staple forming members 172, 17 4 the said grooves receiving the staple legs at the time of formation of the staple. In order to insure that the cross-bar of the staple will not catch upon the upper edge of the controller member 198 in passing downwardly from the end of the inside former 160, the upper corner or" the controller member is beveled oft, as indicated at 202. At the end ot the downward movement of the outside former the staple is located below the lower end of the staple controller member 198 and in the path of the staple driver 204 (Fig. 7), the arrangement being such that the lower end of the outside staple former 171 embraces the bed member 206 of the driver guideway. The result of this arrangement is that the staple legs are confined in a space between the bed member 206 below and shoulders 208 (Fig. 11) which define the upper walls of the grooves 200 in the former members 172, 174, in which the staple was originally formed. Furthermore, the driver bar 204 is guided in the same way as the staple itself, that is, between the guide bed 206 and the shoulders 208 on the former members' 172, 174 and in the grooves 200. It will be understood that the guideway thus formed is in alinement with the driver guideway 210 in the staple guiding nose or nozzle 212 from which the staple is driven .into the work. Since the outside former members 172, 174 must be brought accurately into proper alinement with the wire guides 184 at the upper limit of the movement of the outside former 171 and must also be accurately fitted with relation to the bed 206 so as yto bring the staple into the plane of the driver and yet not pinch the staple or the driver against the bed, means is provided for fixing the limits of the up-and-down movements of the outside former 171 by set screws 214, 216 adapted to engage a lug 218 projecting from the slide bar 176, the `said set screws 214, 216 being adj ustably clamped in position so that adjustment may be made in setting up the machine and in accommodating the parts to any wear that may take place.

For moving the outside former 171 from staple forming to staple delivering position, as above described, there are provided operative connections from a cam wheel 220 (F ig. 1) fixed on the shaft 7l, the said connections comprising a lever 222 pivotally mounted on a pivot 224 fixedly secured in the head frame 58 and havinga roll 226 to engage with the cam wheel 220. At its other endthe lever 222 is pivotally connected to a link 228 upon which is slidably mounted a sleeve 280, a. spring 232 being interposed between the upper end ot the sleeve 280 and the end of the lever 222. As shown, the sleeve 230 is screw-threaded exteriorly, thus providing for adjustment of a hub 234 which surrounds thesleeve and is adjusted upon turning the sleeve, as will be readily understood trominspection ot the drawings, and

m-ore particularly of F ig. 1. Connected to the hub 234 is a rod 236, the lower end oi which is pivotally connected to a projecting arm 238 (Fig. 4) secured to or integral with the former bar 176. For yieldingly maintaining the roll 226 in contact with the cam wheel 220 there is provided a spring 240 Figs. 2 and 3) secured on the Fixed pivot 224 of the lever 222, one end of the spring being connected to the pivot 224 and the other end engaging with a pin 242 on the side of the lever 222 so as yieldingly to maintain the lever in contact with its operating cam. From a consideration of the construction just described, it will be clear that the formerlbar 176 is yieldingly actuated in both its upward and downward movements so that Jche set screws 214, 216 are permitted to determine the positions of rest of the outside former 171 in its staple forming and staple delivering positions.

After the staple has been formed and delivered by the outside former 171, it is driven.

into the work by the staple driver 204, as above described. The means for operating the driver bar comprises preferably a spring llt) which is wound up and then tripped at the proper instant to effect a practically instantaneous staple inserting operation. In the illustrated construction there is pivoted upon an extension from the slide 170 on a pivot bar 248 a driver operating lever 250 having its lower end bifurcated, as at 252 (Fig. 1), to hold adj nstably clamped therein a bar 254 having its lower end swiveled in a block 256 slidably mounted in a driver bar 258 to which is lixedly secured the staple driver 204. vWound around the pivot 248 is a spring 260 (Fig. 4) having one end 261 caught under a shoulder on the lever 250 and its other end secured to a part of the supporting extension of the slide 170, the said spring being relatively heavy and adapted to operate the lever 250 forcibly to effect the'operative stroke of the staple driver. For turning the lever 250 against the tension of the spring 260 there is provided operating means for the outer end of the upper arm of the lever 250, which means is adapted to be tripped at the proper time to permit the operation of the spring 260. In the illustrated construction, this operating means comprises a link 264 (Figs. 1 and 2) pivotally connected at 266 to a slide 268 which is vertically reciprocated by beingrigidly connected with a crank operated slide 269 at the front end of the shaft 71. )Vound upon `the pivot 26S of the link 264 is a spring 270 (Figs. 2 and 3) adapted to move the link 264 yieldingly toward the front of the machine so that its lower end will be pressed into position to engage a shoulder 276 formed on a plate 272 on the link (Fig. 1) with the upper edge of a similar plate 274 carried by the front end of the lever 250. rlhis engagement of the shoulder 276 on thc plate 272 with the upper end of the plate 274 takes place after the upward movement of the link 264, the result.

being that the lever 250 is turned in a clockwise direction to wind up the spring 260 on downward movement of the link 264, the lower end of the rear arm of the lever 250 moving rearwardly to retract the staple driver 204 from the path of the staple which is brought down by the outside former 171. This tensioningl of the spring 260 and the retraction of the staple driver 204 take place at or near the end of the forward movement of the slide 170; and after the slide has completed its forward movement and the staple has been transferred, a cam block 280 adjustably fixed to the front side of the link 264 engages, in the continued downward movement of the link, with a cam surface 282 carried by an arm 284 fixed to a stationary part of the head frame 58, the result of the engagement of the parts 280, 282 being to swing'tlie link 264, causing disconnection of the shoulders on the plates 272, 274 from each other, so that the driver lever 250 is released with the result that the spring 260 immediately operates to shoot the staple driver forwardly to insert a staple into the work. Carried by the slide 170 is a projection 290 in which is mounted by screwV threads a button 292 which may be adjusted by turning the same with the aid of ascrew driver having its end inserted in the slot 294, the rear end of the button 292 preferably carrying a disk of hard fibre 296 which acts as' a buffer againstwhic'h a boss 298 on the lower arm of the driving lever 250 may strike at Vthe termination of the driving movement of the lever.

The wire from which the staples are formed is carried upon av reel 300 (Fig. 3) from which it is fed through the operation of wire feeding rolls 302, 304, the latter being yieldingly pressed against the former by spring means indicated at 305, Fig. 1. For operating the feed rolls there is provided a pawl and ratchet mechanism 306,308v

(Fig. 1) arranged to receive intermittent driving movement from a rocking arm 310 yieldingly backed by a spring 312 on the shaft 314 which is rocked thro-ugh the operation of a cam at the lower end of a vertical shaft 316 which is driven through intermeshing gears 318, 320, the latter being fixedly secured to the shaft 71. The wire feed mechanism is thus brieiy described since it forms no part ofthe invention. Any other well-known wire feeding mechanism may be substituted therefor provided it is adjustable and can be made to feed the wire intermittently in definite amounts to the staple forming and driving mechanism. After the wire leaves the feed rolls 302, 304 it passes through a wire guiding tube 322 (Figs. 1 and 4) by which the wire is directed to a guide block 324 fixedly secured to the bracket 162 which is stationary with the head frame of the machine. From the wire guiding block 324 the wire passes into the slot of Vthe adjacent movable guide blocks 184 and just to the rear of the stationary cutting block 182, theadjustment of the throw of the feed rolls being suoli as to carry the wire across the space at the rear face of the inside former 160 and into contact with the adjustable abutment 186. The end of the wire is thus in position to be cut 0H;1 through the operation of the movable and stationary cutters 180, 182, as before described. v

In the preferred embodiment of the invention shown, the cam 70 is shaped to relax gradually the tension of thespring 72, if it be under tension due to a strong updraw of the upper of theshoe, and then to depress bodily the gripper jaws 30, 42, the cam being timed with the movement of the nose 212 to overlay theupper on thek sole, the gripper moving downwardly as the overlaying' member 212 moves to press the upper down upon the sole.

It will be understood from thel foregoing description that foreach staple driving Voperation a staple s having straight legs is formed and is transferred into the path of movement of the staple driver 204. For anchoring the staple in the work there is provided means for bending the legs of the staple progressively as the staple is driven by engag- V ing them at the same side of the work from which the staple is driven, so that they take curved paths in the work. For this purpose thereis mounted on the staple guiding nose 212 a detlector comprising a pair of bending members 406 pivoted on a stud 402 which is carried by a bracket 404 on the member 212. The members 406 at their lower ends are notched at 411 to provide surfaces positioned in the line of drive of the staple legs for engaging said legs and deflecting them in a positively predetermined manner during the driving of the staple while guiding them in predetermined planes extending transversely of the plane of the staple, i. e., the plane defined by the legs and the crossbar prior to the deflection of the legs. As herein illustrated, the staple deflector is thus so positioned and shaped as to bend dilierent portions of the legs of the staple successively, before said dierent portions enter the work, to the same positively determined degree, thus giving all portions of the legs ofthe staple that enter the workV a substantially regular curvature and causing them to take predetermined curved paths in the work. In the construction shown the legs are Ycurved in arcs of such radius that their ends return toward that surface of the work at which they entered. By bending the legs of the staple in this manner, the deflecting means determines likewise the depth ot' penetration of the staple into the work.

In the construction shown each of the members 406 is adjustable independently of the other about its pivot 402, so that the different legs of the staple may be differently curved if desired, and set screws 408 and 410 are provided for adjusting each member and for holding it firmly in adjusted position. It will be seen that by adjustment of either member 406 about its pivot its lower deflecting end may be positioned at different distances from the end of the staple guiding nose 212 from which it is spaced, thereby determining with great precision the curvature of the staple legs. It will be further evident that since the staple guiding nose 212 positively guides the legs of the staple in a plane transverse to the direction of the bending effected by the staple delector until the legs emerge from the guideway insaid nose, the bending is confined at anyone time to a comparatively smallportion of the length of the staple legs, and this is an important factor in the accurate control of the degree of `curvature imparted to the legs.

In using the machine to last the sides of ay shoe, for example of the through-andthrough sewed type, a shoe in the usual condition for side lasting is positioned with its insole in engagement with the sole rest 150 and With the side of the shoe in Contact with a gage member 420 which may be provided in addition to the sole rest to assist in positioning the shoe accurately for the dierent operations.V It will be seen that the shoe herein shown is provided with an insole a having a plane bottom face. In the operation of the machine the upper b is pulled by the the upper about the edge of the insole under lasting strain and to lay a portion of its margin in parallel relation to the bottom face of the insole. In this overlaying operation the gripper, while retaining its grip on theupper,

relaxes the force of its pull in the manner hereinbefore explained. VJhile the upper is held under lasting strain, as herein shown by the gripper and by the pressure of the overlaying means, the staple s is driven in a location in the line of the lasting strain and is anchored in the intact substance of the insole in the manner illustrated progressively by Figs. 14 and 15. It will be seen that the staple, driven in a direction inclined to the plane of the insole at the same angle as the direction of the overlaying movement of the overlaying means, is deflected so that its legs enter the shoe materials in substantially perpendicular relation to the plane of the insole and then take predetermined curved paths in the materials. As herein illustrated the legs of the staple are bent in arcs of such radius that without penetrating to the inner face ot the insole their ends are directed reversely toward its bottom face. staple legs thus driven may or may not emerge from the bottom face of the insole, since in either case they are covered by or embedded in the shoe bottom materials after the outsole has been applied. In the operation of the machine herein shown the legs of the staples are turned outwardly toward the edge of the insole from the points where they enter the insole, but are driven at such distances from the edge as to afford room for-the line of outsole stitches between the edge of the insole and the line of staples. f

It will be understood that after the operations above described have been performed in one location and the gripper has released the upper, the shoe is moved along to a differ- The ends of thet l'lO ent location and the same lasting operations Y are repeated. In this manner the sides of the shoe are lasted progressively, the upper bel ing fastened securely and permanentlyy in lasted position by the staples Without opportunity for it to relax between the upper pulling and the fastening operations. It will be seen that the staples are driven into the intact substance of the insole and that secure anchorage for the legs of the staples is thus afforded even though the insole may be comparatively thin. By reason of the accurate predetermining of the curvature of the legs of the staples independently of resistance of the shoe materials, a comparatively thin and flexible insole may be utilized Without penetration of the staples entirely through it.

The novel method of shoemaking herein disclosed and novel features of the shoe are claimed in a separate application Serial No. 724,135, filed on July 3, 1924. Furthermore, novel features of the means disclosed for fastening an upper to a` sole and in general for driving and anchoring fastenings are claimed in a divisional application Serial No. 198,179, filed on June 11, 1927.
